+PROTOCOL is the type of protocol being registers (http, nntp, etc),
+and is the first chunk of the URL.  ie: http:// URLs will be
+handled by the protocol registered as 'http'.  PROTOCOL can
+be either a symbol or a string - it is converted to a string,
+and lowercased before being registered.
+RETRIEVE (optional) is the function to be called with a url as its
+only argument.  If this argument is omitted, then this looks
+for a function called 'url-PROTOCOL'.  A warning is shown if
+the function is undefined, but the protocol is still
+registered.
+EXPANDER (optional) is the function to call to expand a relative link
+of type PROTOCOL.  If omitted, this defaults to
+`url-default-expander'
+Any proxy information is read in from environment variables at this
+time, so this function should only be called after dumping emacs."
